What is used for your software quality?

Hello everybody.
We are a small group of CS-Students from Germany. We got the task to interact with an open-source project (we chose yours) and check for the quality of your software or, if possible, to improve it. For those reasons we wanted to ask if you use any software like SonarCube / SonarLint or anything similiar. If so, could you link me the documentation of it, since I unfortunately haven’t found it in your README.md on GitHub.
We are looking forward hearing from you.
Greetings!

We don’t use this at the moment.
